Earthquake Retrofitting questions, answered by experts

According to the Earthquake Country Alliance—a public and private alliance in California that works to improve earthquake and tsunami readiness—reports that unreinforced masonry, such as stone, bricks, and hollow clay tiles, is more susceptible to earthquake damage. The mortar between bricks isn’t as stable as other building materials and methods.

The average cost for an earthquake retrofit is between $3,500 and $8,700, though the full range can be anywhere from $500 to $15,000 or more. Costs vary significantly depending on your home's foundation, type, and the specific retrofitting method used. For a slab foundation, you can expect to pay on the lower end, between $500 and $3,000, while a wooden foundation can cost $5,000 to $10,000. Retrofitting a hillside home typically costs between $5,000 and $12,000 or more. A soft-story home, such as one with rooms over a garage, is the most expensive, with costs ranging from $10,000 to $80,000. It is advisable to get multiple estimates to compare services and pricing.

First, you can expect the project to be loud. If you have pets, you might want to take them to a friend's house during the day so they are not disturbed by any of the loud noises. In addition, you’ll need to provide the retrofit team access to areas of the house that will need to be worked on, meaning you’ll need to relocate personal items, clear clutter, and make pathways for the crew. Once the project is complete, a local building inspector will conduct a final inspection to ensure that the retrofitting is up to code.

Whether an earthquake gas shut-off valve is required depends on your location and circumstances. Certain cities, states, and even insurance providers mandate them, especially in areas with high seismic activity. In California, for example, while laws vary by county, most jurisdictions require a valve to be installed in newly constructed homes or when a home is sold or renovated. The Los Angeles Municipal Code specifically requires a licensed contractor for installation. Even if not required by law, installing a seismic shut-off valve is a wise safety measure. These devices automatically cut off the flow of gas during an earthquake, which can prevent gas leaks, fires, and explosions. It is recommended to check with your local building department for specific laws regarding installation, permitting, and inspections, and to ensure the valve you install is on your city's list of approved models.

Ensure proper ventilation, fix leaks, and schedule regular pest inspections to protect your property.
